In many pitch presentations, I work hard to lift a story to its true potential. Show the bigger picture, put things in a historical context of where humanity is going, visualise the - dreaded word - vision.
In some presentations the opposite is required. The audience will get the dream, but will wonder whether any of this stuff is actually real, or happening within the next 2 years or so, because it all sounds too good to be true, or too expensive, or too science fiction.
Thinking about your audience before you start designing is a cliche from communication trainings. Maybe make it a bit more practical and try to imagine what stereotype people would assign to you after they see/hear you speak for 1 minute.
